Apparently that is the old initial thrust range requirements for the high-bypass variant of the WS-15.

A TV segment on the JF-22 hypersonic wind tunnel reveals that an oblique detonation wave engine (using aviation kerosene) was tested in JF-22's predecessor, the JF-12 hypersonic wind tunnel, and the engine has achieved stable operation at Mach 9. Next, the engine will be tested in JF-22 at up to Mach 16.

WS-13 turbofan's development timeline from a book published by Liyang. Corrections appreciated.
- 2002: pre-research on critical components and technologies completed.
- 2003: August, engine core design completed; October, the project for engine core development officially commenced; December, the engine was given code name 'Taishan' (泰山) by Air Force leadership.
- 2004: demonstrated the feasibility of the medium-thrust engine project.
- 2005: June, the initial test of the engine core was a success; September, the Taishan engine project officially commences; October, full-engine prototyping commenced; November, engine core completed its fourth test run.
- 2006: chief of the Logistic Support Department of the Central Military Commission put forward the requirement that Taishan be used to power UAVs in the future; December, first prototype engine achieved stable test bench operation.
- 2007: December, the second prototype engine achieved 150 hours of stable operation.
- 2008: May, Taishan passed high-altitude test; June, development for a non-afterburning variant (intended for UAVs) officially commenced.
P.S. According to the book, the WS-13 began as a self-funded project without any financial support from the state.

A preview of what's on display at this year's Tianjin Helicopter Expo.
A new 1100kW turboshaft to power helicopters in the 5-6 ton class. It has built-in protection system against sand and other particles. Features built-in health management system:
A new hydrogen-fuel turboshaft (1000kW class) to meet low carbon emissions goals:
A hybrid electric propulsion unit (80kW class). It's being tested on light sport aircraft:
